CAR-DUMP FOR ELEVATORS IN MINES,

SPECIFICATION formingpart of Letters Patent No. 692,888, dated February 1 1, 1902.

Application filed November 22, 1900. Serial No. 37,359. (No model.)

To all whmn it may concern:

Be it known that 1, JOHN MOSES, a citizen of the United States, residing at Youngstown, in the county of Polk and State of Iowa, have invented a new and useful Car-Dump for Elevators in Mines, of which the following is a shafts and to facilitate the labor of unloading cars without disconnecting them from an elevator'cage.

My invention consists in the construction, arrangement, and combination of parts, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which- The letters A designate the uprights fixed in a shaft to support and guide a cage in its up and down movements.

'B designates the bottom, and B the top, of.

a cage, rigidly connected by means of a plurality of iron bars 0 or in any suitable way.

C is a cable fixed to the top of the cage for hoisting and lowering it.

Track-rails D are pivotally connected with one edge of the floor or bottom B of the cage by means of hinge-irons D fixed to the rails,

and a bar D fixed to the cage, or in any suitable way so the free ends of the track-rails can be elevated as required to tilt a car F, supported on the rails.

The cage and cars are shown only in sections, and consequently only one of the track-, rails appears. In its normal condition the car rests on the track-rails when they are level, as shown. Hook-shaped stops D are fixed to the cross-piece at the top of the shaft in such a manner that when the track-rail D and the car are elevated and the track-rails raised at their free ends, as required to tilt the car so that it will move outwardly, two

of the mating car-wheels will be engaged by the stops D and the car retained in an inclined position to discharge its contents.

D represents a brace fixed to the stop D and a portion of the frame in the shaft.

A block g is fixed on the top and center of the floor of the cage, and detents g are pivoted to the block in such a manner that they will engage an angle-iron it, that is fixed to the bottom of the car, and prevent the car from moving on the track-rails when they are level. These detents serve as inclined planes relative to the horizontal movement of the angle-iron 71, and are operated by force of gravity to engage said iron when the trackrails and car are level on the floor of the cage.

Frames J are pivotally connected at their lower ends with the uprights Aand connected with each other by means of rods J pivoted to their top ends. J 3 is a rod pivotally connected with the ends of the rods J and a lever J that is fulcrumed to the frame in the shaft in such a manner that the frames J can be placed in position by means of the lever, as shown and as required to allow the cage to move down in the shaft. In their normal condition the frames J occupy positions as indicated by dotted lines and as required to allow the cage to pass upward and to move outward and under the cage to prevent any downward descent of the cage before they are adjusted by means of the lever J K is a rock-shaft journaled to the uprights A, and m represents props fixed to the shaft and adapted in form to engage the free ends of the track-rails D, as required to retain the rails in inclined position and as required for tilting and unloading the car.

N is a hand-lever fulcrumed to the frame in the shaft and pivotally connected with an arm K on the rock-shaft K by means of a rod N in such a manner that the props m can be readily drawn under the ends of the track-rails when they are elevated, as required to retain the track-railsinclined'while a load on the car is being dumped therefrom.

Pis a spring fixed to the frame in the shaft and to the lever N in such a manner that it will normally retain the props m in a perpendicular position, as shown.

To tilt and unload a car when it is elevated on the cage and the cage is prevented from descending by means of the pivoted frames J, I hoist the cage farther, so as to allow the props m on the rock-shaft K to be inclined inward by the operation of the hand-lever N, and then allow the cage to descend again, so that the props art will engage the free ends of the track-rails D so they will be retained and the rails inclined, while the fioor of the cage carrying the block g and detents g is lowered and the angle-irons h on the bottom of the car released, so as to allow the car to move outward and downward on the inclined track as far as the hook-shaped extensions D of the rails will allow the front wheels to go and as required to dump the contents of the car therefrom. When a car is thus advantageously unloaded,'it can be readily replaced in a level position in the cage by adjusting the props m by means of the lever N, as required to level the track-rails D.

Having thus described the purpose of. my invention and the construction, f auction, and operation of each part, the practical utility thereof will be obvious to persons familiar with the art to which it pertains, and a What I claim as new, and desire to secure by Letters Patent, is

1. A cage in a shaft for elevating minerals, detents pivotally connected with the top and central portion of the floor of the cage, trackrails pivotally connected with one edge portion of the floor, a car on the track-rails, an iron fixed to the bottom and central portion of the car to engage said detents, a rock-shaft journaled to the frame in the shaft, props fixed to the rock-shat t for supporting the track-rails in an inclined position, an arm on the rockshaft, a coil-spring fixed to said arm and to a lever, a lever fulcrumed to the frame for operating the rock-shaft and props and means for raising and lowering the cage, arranged and combined to operate in the manner set forth for the purposes stated.

2. A car-dump for elevators in mines, parallel uprights fixed in a shaft, frames pivotally connected at their lower ends to the parallel shafts, rods pivotally connected with the upper portions of said frames, a lever connected with the rods forad j usting the frames, a cage fitted between the parallel uprights, track-rails for a car pivotally connected with one edgeportion of the floor of the cage, hookshaped stops fixed to a cross-piece at the top portions of the uprights for engaging carwheels, detents pivoted to the top and central portion of the floor of the cage for detachably fastening the car, a car on the track-rails, an iron fixed on the under side of the car to engage said detents, a rock-shaft journaled to the uprights of the frame in the shaft, props fixed to said rock-shaft to support the free ends of track-rails, means for adjusting said rock-shaft and props and means for raising and lowering the cage, all arranged and combined to operate in the manner set forth for the purposes stated.

JOHN MOSES.
